It used to be the case that some batteries would last longer if they were regularly fully discharged. With the latest technology, I don't think it matters much when you put them on charge. I've had my iPhone 5S for over 3 years, and it gets put on charge every night. Also, it used to be topped up at lunchtime, when I was using it more heavily. The battery still lasts very well for the whole day.

I too have a iPhone 5S and the battery life is equally long. The previous phones I've had (including Android) worked best by draining the battery to the end. However, I would be forced to charge before 25% as the battery sometimes randomly shut off beyond this point.

Even though I do think there are ideal charging points, sometimes our schedules don't allow us to charge our phones when we want. In particular with myself, I can't afford for my phone to die throughout the day as I always have to stay in communication with certain people I find important in my life.

Any specific level to comply with? I will only re-charge it when it appears with the low battery signal, I think it's about 15%.

[skysnap]

My battery seems to be acting out. I have to charge after 10% these days otherwise it goes down quickly

[ladyninja]

I charge my cell phone battery when its about 10%. I read somewhere its not advisable to let your cellphone battery drain out completely before charging it.

[amitkokiladitya]

I do most of my online work through my phone so I keep charging it every now and then. Whenever I'm not working I attach it to the charger. This keeps my phone about 80% charged most of the times.

[ruthmongare]

When it reaches 4% so that I avoid destroying the battery since mine is inbuilt and thus I avoid charging it every time.

[MAYENZ]

I normally charge it at 10% battery

[ruthmongare]

When my battery reaches 15%, it switches to battery saver mode and has an orange bar across the top. When I see the orange bar, I know I need to charge my phone soon.

There is no fixed rule for me but I never let it go below 40 anyway. I keep my phone's battery charged as soon as I feel it needs a recharge.

Yes there's no limit but one shouldn't charge it frequently to avoid spoiling the battery.

[southernfried18]

If I'm near a charger I try to keep it plugged in.

[Musati]

Well according to recent research on Lithium batteries you should constantly keep your phone charged to enable prolong the battery life. Once it reaches 100% unplug it from the power source. So for me i tend to charge at any slightest moment that i find a power source. It may be at 70% or 80% or even 50%

[Little Mage]

I texts and chats so much on my phone that somtimes my battery dies ! I have to charge it, or it will go crazys. But yes sometimes don't charge till it's zeros

[raaman]

I was having the habit of charging it every now and then but recently my son told me that I should charge it only when it reaches 15% or else the battery will get spoiled. How far it is true, I do not know.

[sprite1950]

I let mine get low but if I am going out and I don't want it to die on me I will charge it at something like 20% because I hate being without a phone.

[darrensurrey]

I do it any time it's under 90% especially if I know I'm going out that day. Otherwise, I just let it drain as low as 30%.

[tabzy24]

20% most of the time.. but once a month i totally drain it bfore i charge..

[MattTolentino02]

Do not let the battery reach 0%. It will shorten its life.

[sabtra]

I think it's correct when the smartphone tells you to do so, it knows what it needs and when it does.
Unfortunately there are times I charge it when it's 0%, when it's in a coma, so to speak.
Otherwise, below 20%, around 10% most of the time.
If it's above that percentage, I will just wait and avoid using it if I'm not at home.

[lisasteinmetz69]

I will usually let it get to 10% before I charge it if I'm out of the house. While at home I keep it plugged in 24/7.

[neuralnet]

I'll usually charge my phone, any time when I can, when it be overnight, in the car, or when I'm not using. Or at least I try to. If not, I'll usually charge my phone at around 20%.

[DaveHenryy]

You might not believe me for this but I usually charge my phone at 1%-3%. I just believe that I have charged my phone to a 100% and now it is fine to use as much battery as I can.
